Twin Falls County is the 6th most populous county in Idaho with 77,230 residents. In early years, the county area was an unorganized part of Shoshone lands, then as part of the Oregon Country. Its name comes from a split waterfall on the Snake River with the river being the northern boundary. More settlements and populations gravitated toward the Twin Falls County area after 1904 when the city of Twin Falls was founded and when the Milner Dam was completed.
Twin Falls County boasts many recreational opportunities and cities including Buhl, Castleford, Filer, Hansen, Hollister, Kimberly, Murtaugh, Rogerson, and Twin Falls. Residents and visitors alike can take part in water recreation in the Snake River and explore surrounding destinations.
